If you installed .NET 2.0 before you installed IIS, you may receive a “Failed to access IIS metabase” error.
You will need to repair your ASP.NET installation and set up the appropriate ISAPI extension mappings.
To do so, follow these steps:
Open the Control Panel.
Open Add/Remove Programs.
Scroll down and select .NET Framework 2.0.
Click Change/Remove. The Maintenance Mode dialog box appears.
Select Repair.
Click Next. Follow all of the prompts.
If the above steps did not work, try the following:
Select Start > Run. The Run dialog box appears.
Type C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i
Press OK. A command window appears, and your ASP.NET installation will be repaired.
When complete, your API connection should work normally.
